Chapter on Ruling of the Traveller and the Sick Person Regarding Fasting

And that which Muhammad ibn Yaqub narrated from Ali ibn Ibrahim, from his father, from Ibn Abi Umayr, from Hammad ibn Uthman, from al-Halabi, from Abu Abdillah عليه السلام, peace be upon him: Imam عليه السلام was asked about ‘a man who leaves his house while intending travel and while he is fasting.’ Imam عليه السلام said: “If he leaves before the day reaches its midpoint, then let him break the fast and make up that day. But if he leaves after midday, then let him complete his day.”
